Q

Does anything happen within the nurse call system if a bedside call station wall assembly has no cord connected to it?

A

Yes, because the bedside call station is part of an electrically supervised system, no cord in the wall assembly will initiate a call.

28
Q

What effect does a failure in one part of a nurse call system have on the rest of the system?

A

The remaining system operates normally.

Self Test 1

29
Q

Where is the logic or controls for any patients room located?

A

In the components of that room.
Each room acts independently from every other room and sends signas to central control.

30
Q

What are the advantages of a wireless nurse call system?

A

Nursing staff know immediately from anywhere in the hospital which patient initiated a call and can communicate by voice with the patient.

Self Test 1

31
Q

CMOS is susceptible to damage from static discharge.

A

True

LT2 Pg21

32
Q

What happens to the system, or other rooms, when there is a fault in one room?

A

A fault in one room does not effect any other room.

LT2 Pg21

33
Q

What may be considered a zone?

A

A wing, corridor, or specialized area.

LT2 Pg21

34
Q

If the nurse call system is interconnected with other systems within the facility (entertainment, phone, computer patient monitoring), what stringent guidelines must be ensured?

A

Must have electrical isolation from other systems
The failure of any other system will not have an adverse effect on the operation of the nurse call system

LT2 Pg21/22

35
Q

What class of wiring does the CEC designate to nurse call wiring?

A

Class 1

LT2 Pg24

36
Q

What does a class 1 designation do for nurse call wiring?

A

Requires that the cabling must be kept clear of communication cabling, power conductors, lighting conductors. This separation reduces the possibility of interference.

LT2 Pg24

37
Q

What is a UPS and what does it accomplish?

A

Uninterruptable Power Source
It ensures that the nurse call system is always connected to power.

LT2 Pg24

38
Q

ULC-1069 requires that all circuits in patient care areas be limited to what VA?

A

100VA

LT2 Pg25

39
Q

ULC-1069 Nurse Call Equipment - maximum voltage and power.

1) Max voltage available to equipment installed in areas accessible to patient
2) Max power available to low voltage equipment installed in areas accessible to patient
3) max voltage to control circuit where wet location contact is likely

A

1) 30v AC, 42.4v DC
2) 100VA
3) 15v AC, 12.4v DC

LT2 PG25
Rule 16-222(3)

40
Q

Why is a nurse call system tested by an independent testing contractor after installation?

A

To ensure the system meets the requirements of the CSA

LT2 PG25

41
Q

What is the maximum amount of time a nurse call system can be without power?

A

10s

Self Test 2

42
Q

What are the bonding requirements for a nurse call system?

A

Bond must be sized in accordance with table 16, but in no case can be smaller that #12AWG

Self test 2

43
Q

What are the requirements of the branch circuit supplying a nurse call system?

A

24-102
A separate circuit of #12 AWG copper or larger, at not more than 150v to ground supplied by an essential electrical system

Self Test 2

44
Q

What is an essential electrical system?

A

An electrical system in which the interruption of that system may compromise the care, safety, and health of patients.

Self Test 2

45
Q

What and/or where are the indications when a patient initiates a call?

A

Corridor indicator
Zone indicator
Floor control station
